This radon test includes regular mail to the lab, which I like. Production time was within a week of shipping. Turnaround time for the competitor's radon test is just over a week from receipt of test if there is no rush and shipping is not included (an additional $3.50). This test takes an extra day at home, 3 days instead of 2, but I didn't care. The result seemed reliable. If you need to do multiple radon tests, this is one way to avoid going broke.
